Overview
prEN ISO 8367-1 (ISO/DIS 8367-1:2025) specifies dimensional tolerances for general‑purpose paper sacks. It updates the earlier edition (ISO 8367-1:1993) and defines acceptable manufacturing tolerances for key sack features such as ply grammage, sack length and width, gusset and bottom dimensions, valve and sleeve sizes, and print positioning. The draft references measurement and sampling methods (ISO 536, ISO 6591‑1, ISO 7023) and notes that closer tolerances can be agreed between purchaser and supplier.
Key topics and technical requirements
- Grammage tolerances
- Single paper ply: ±4 %
- Single coated paper ply: ±6 %
- Total sack plies: ±4 % (sum of plies may compensate individual deviations)
- PE film (laminate) tolerances
- < 10 µ: ±20 %
- 10–30 µ: ±15 %
30 µ: ±10 %
- Dimensional tolerances (typical)
- Length of sack: ±10 mm
- Width of sack: ±5 mm
- Width of gusset: ±5 mm
- Bottom widths (both sides): ±5 mm
- Circumference (with gussets): ±15 mm
- Valve and sleeve
- Valve opening (pasted): +5 / -0 mm
- Valve opening (sewn): +10 / -0 mm
- Valve sleeve width: +5 / -0 mm
- Valve length (in formation): ±5 mm
- Valve sleeve length: ±10 mm
- Print position tolerances
- Length direction: ±20 mm
- Width direction: ±10 mm
Measurement and sampling methods are referenced to ISO 536 (grammage), ISO 6591‑1 (dimensions & measurement) and ISO 7023 (sampling of empty sacks).
Applications and who uses it
- Sack manufacturers and converters: to set production tolerances, control quality and reduce rejects.
- Packaging specifiers and purchasers: to define acceptance criteria in purchase orders and supplier contracts.
- Quality assurance teams: for incoming inspection, sampling plans and conformity assessment.
- Filling and handling equipment suppliers: to ensure sacks meet dimensional requirements for reliable filling, valve fit and machine handling.
- Regulatory bodies and standards committees: as a reference when harmonizing national rules or industry best practice.
Benefits include clearer supplier–buyer agreements, fewer disputes over dimensional nonconformities, and improved compatibility with filling and closure systems.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of
